The focus state persists even after the DOM element has been modified

I am currently utilizing Vue along with Bulma.

My challenge lies in updating the DOM upon a button click event. Even after the update, the button still retains its focus state.

I aim to have the updated button without the focus state. What would be the most effective approach to tackle this issue? Is there a more conventional way within Vue.js to address this common scenario?

Find below a simplified example:

var app = new Vue({
  el: '#app',
  data: {
    options: [{
      text: "This is the first text"
    }, {
      text: "This is the second text"
    }, {
      text: "This is the third text"
    }],
    index: 0,
  },
  
  methods: {
    nextText: function() {
      if (this.index < this.options.length - 1) {
        this.index++;
      } else {
        this.index = 0;
      }
    }
  }
})

<div id="app">
  <button v-on:click="nextText()" class="button is-primary is-outlined">{{ options[index].text }}</button>
</div>

Answer №1

I resolved this issue by compelling Vue to refresh the button element.

In my specific scenario, it is necessary for the button to function as a new button without retaining any previous 'focus' state.

This can be accomplished by adding the :key attribute to the button element.

<button v-on:click="nextText()" :key="index" class="button is-primary is-outlined">{{ options[index].text }}</button>

See the updated code snippet below.

var app = new Vue({
  el: '#app',
  data: {
    options: [{
      text: "This is the first text"
    }, {
      text: "This is the second text"
    }, {
      text: "This is the third text"
    }],

    index: 0,
  },

  methods: {
    nextText: function() {
      if (this.index < this.options.length - 1) {
        this.index++;
      } else {
        this.index = 0;
      }
    }
  }
})

<div id="app">

</div>
